Sherlock Holmes at Hogwarts.

Chapter 79 Leaving Tonight
"We're leaving tonight?"

Harry asked in a low voice.

"The students won't arrive until tomorrow night. Filch will be less alert tonight than usual, which is a good opportunity for us."

Harry readily agreed.

Harry became even more excited when he put on the invisibility cloak and saw his body completely disappear from sight.

Before leaving, he hesitated for a moment and stretched his invisibility cloak a little wider:
"Sherlock, why don't you come in too?"

Harry's idea was simple.

The invisibility cloak his father left him was large enough to cover both him and Sherlock.

Although it may be a little inconvenient to walk like that, the safety factor is high enough.

To be honest, when Sherlock gave him the Invisibility Cloak, he had a bold idea:

Put on an invisible cloak and walk around the campus alone.

Because this was something his father left him, he felt he should use it alone for the first time.

but.

He quickly put the thought behind him.

This is what Sherlock fought for himself, how could he do this?
Without Sherlock, I might not be able to get it!
Although Sherlock said that Dumbledore would give it to him as a Christmas gift, who can say for sure about things that have not happened?

This kind of thinking of mine is really too much!

Harry was ashamed of this for a while.

However, he never expected that when he proposed to share the invisibility cloak with Sherlock, the latter said:

"From the moment I gave you the Invisibility Cloak, you were supposed to wear it and explore the campus on your own.

If you had done that, it would have greatly helped us in our actions today."

Harry's head snapped up.

"It's a shame that this wasn't the first time you used it until today."

"I……"

"As for now... just put it on and don't talk. Just walk in front."

Sherlock's voice was calm, but his tone was full of confidence. "Even without the invisibility cloak, I won't be discovered."

His refusal was so firm that Harry had no choice but to agree.

But his heart was in a mess.

It turns out that in Sherlock's opinion, his previous somewhat selfish idea was actually correct?

Isn't that outrageous?
He calmed himself down and asked again, "But... where are we going?"

"Go wherever you want. Don't worry, I'll follow you."

This is Sherlock's purpose.

Taking Harry on a night tour of the campus tonight, with no specific destination.

The main purpose is to increase knowledge and improve experience.

Just as he had just said to Harry, from the moment Harry decided to face Voldemort, Sherlock decided to make Harry stronger.

Otherwise, if Harry relied solely on the ancient spell and his passion to face Voldemort with his current immature means, he would be asking for his death.

Next, Harry put on the invisibility cloak as Sherlock had requested, tiptoed out of the dormitory, down the stairs, through the common room, and crawled through the portrait hole.

"who is that?"

The Fat Lady asked in a gruff voice, unable to see anyone.

At this moment, Harry's heart was beating fast.

He remembered Sherlock's words well, remained silent, and just walked quickly in the corridor.

He didn't even dare look back to see if Sherlock was following him.

At the same time, Sherlock, who was following behind Harry, couldn't help but shake his head secretly.

If it weren't for the Invisibility Cloak, Harry would have been discovered as soon as he left the common room.

Even with the help of the invisibility cloak, Sherlock still saw many flaws in Harry's stealth posture.

Fortunately, they still have time.

Reaching the end of the corridor, Harry finally had time to catch his breath.

He stopped and prepared to choose his destination.

However, just when he subconsciously wanted to discuss it with Sherlock, he was surprised to find that Sherlock was missing!

This frightened Harry.

He looked around again, making sure Sherlock was not there, and couldn't help but call out softly:
"Sherlock? Sherlock!"

There was no movement.

He was the only one in the corridor.

Oh no, did I walk too fast and lose Sherlock?
This thought immediately made Harry feel uneasy.

Yes, although Sherlock is powerful, he is invisible now after all.

I was in too much of a hurry just now. I should have slowed down and waited for him.

Thinking of this, Harry no longer hesitated and turned around to go back.

He would never abandon his friends!

However, just as he took a step, a strong hand held down his shoulder.

At the same time, a familiar voice sounded beside his ear: "Good evening, Harry."

"Sherlock!"

Harry turned around in surprise and found Sherlock right next to him.

"Keep your voice down, my friend, if you don't want to attract others." "I, I thought you were with..."

Harry was too embarrassed to say the rest.

It was clearly him who was wearing the invisible cloak, but not only did he not keep an eye on Sherlock, he even thought Sherlock had lost him.

"Where were you?"

Sherlock took two steps to the side and leaned his back against the shadow of a huge stone pillar.

"Tracking and concealment are originally a skill.

Wearing an invisibility cloak makes you invisible to others, but it doesn't mean you actually disappear."

He pinched a thin, glistening piece of glass between his fingers. "A minute ago, you were standing in front of the knight's armor. The temperature of the kneepads has risen two to three degrees Celsius. The invisibility cloak can't block heat conduction."

Only then did Harry discover that there was a prism embedded in the collar of Holmes' robe, and the refracted light network just happened to faintly cover the area of ​​​​the corridor.

"This is... you've already mastered the Disillusionment Charm? That's an advanced spell!"

Harry just found it incredible.

"You really overestimate my abilities, my dear Harry. It's much simpler than that."

Sherlock said, raising his right hand, "Look!"

The thin thread dangling from his fingers shone with a pearly sheen in the moonlight. "This is the spider silk I bought from Diagon Alley last time. If used properly, it can change the direction of light refraction..."

Also, when the invisibility cloak brushes against it, it produces a C major note."

After saying this, he took another half step forward.

"Your breathing rate is 17% faster than normal. Although I don't think others can notice this, I still recommend that you try to relax.

Well, my friend, if you still can't make up your mind, then I suggest you go to the library first.

The distance is moderate, the space is spacious, and you are relatively familiar with the environment there.

If we stay here like this any longer, I'm afraid we won't have much time left."

Harry accepted Sherlock's suggestion without hesitation.

The library was pitch black at night.

Harry didn't know if it was an illusion, but he always felt that this place was particularly eerie and scary compared to during the day.

In this case, Harry had to light a lamp and carry it through the rows of bookshelves.

The lamp seemed to be suspended in mid-air, and although Harry had the feeling that he was holding it in his hands, the sight still gave him the chills.

This feeling reached its peak when he reached the restricted books section at the back of the library.

Harry carefully stepped over the rope that separated these books from the rest of the collection. He was just thinking about taking one out to examine it when he heard Sherlock's voice beside him:

"If I were you, I wouldn't go to areas where footprints are likely to be left."

Harry was stunned for a moment, looked down at his feet, and then chose another path with an embarrassed look on his face.

During the rest of the night's stroll, Sherlock taught Harry a lesson.

Just like before in the corridor, Sherlock made his way through unhindered thanks to his agility and some simple spells.

Instead, it was Harry, who was wearing the Invisibility Cloak, who was almost discovered by Filch on his night patrols several times.

Fortunately, Filch today was much more relaxed than usual, just as Sherlock said.

With Sherlock's support at the critical moment, he was able to get away with it.

What made Harry even more speechless was that there were several times when it was Sherlock's turn to lead the way and he almost lost them.

Even with an invisible cloak, you can still lose track of me...

Shame on you!
On the other hand, Sherlock could always find Harry accurately even though Harry was invisible.

One word, absolutely!

Sherlock took Harry for a walk and reminded him of some stealth precautions. Seeing that the time was almost up, he prepared to return to the dormitory.

On the way back, Sherlock deliberately chose a different route from the one he took coming here.

Harry didn't disappoint at all.

he's lost.

Seeing Harry enter every door and turn every corner, Sherlock couldn't help feeling helpless.

Cultivating a savior is a long and arduous task...

Or... just do it yourself?
Just as Sherlock was thinking about this question, Harry's voice suddenly came to his ear, "Sherlock, are you there?"

Sherlock sighed and walked quickly into the room where Harry was.

"Sherlock, look...what is that?"

Sherlock didn't immediately look at where Harry pointed, but first glanced around the room.

Many tables and chairs were piled against the wall, forming large black shadows in the moonlight.

Coupled with an upside-down wastebasket, it is obvious that this is an abandoned classroom.

Then Sherlock turned his gaze to the object that had caught Harry's attention.

This is a very magnificent mirror, reaching up to the ceiling, with an ornate gold frame and two claw-shaped feet.

Sherlock quickly concluded:
"This mirror was recently moved here, no more than three days ago, and it will be moved somewhere else soon."

"Tell me, Sherlock, how did you know that?"

The Harry now is no longer the Harry who just met Sherlock.

The reason why he just gave up when faced with such a situation was, on the one hand, because he knew that no matter how much he thought about it, it would be difficult to come to the correct conclusion.

Another aspect is that Sherlock himself is very happy whenever he tells his reasoning process.

Especially when he heard others' sincere praise, he could not hide his pride.

In that case, just praise it!
